10 Air Interface (3/5): Carriers Carriers available in the network Bandwidth of carrier ( thermal noise) Multiple carriers in different frequency bands can be used in one project (same bandwidth for all carriers required) Arbitrary carriers can be assigned to a BS TDD or FDD mode can be selected (identical for all BS in whole network) TDD mode: Ratio between UL and DL (e.g.: 1:1 or 3:1) can be defined for whole network FDD mode: UL-DL carrier separation can be defined (identical for all carriers) Carrier definition by AWE Communications GmbH 10

13 Definition of Parallel Used Codes Definition of multiple codes for higher data rates (e.g. HSPA) Increase of own cell interference in addition to interference due to predefined cell load Required Tx power increased Limitations given by Eb/N0 target and the max. Tx power Results on transmission mode level consider only single code Throughput results consider the parallel used codes by AWE Communications GmbH 13

14 Definition of Cell Load (Interference) Definition of relative transmit power if no traffic is considered Interference (Eb/N0) calculation influenced by this parameter Value indicates how much of the data transmission power should be considered for the interference calculation 50% means 50% of the linear data transmission power (in Watts) Data transmission power is calculated based on total transmit power, the power split (data/pilot) and the power backoff value Cell load can be defined globally or individually for each transmitter Definition of noise rise in uplink by AWE Communications GmbH 14

16 Simulation Results Cell assignment Cell area, site area, best server Max. number of received carriers/transmitters/sites (in downlink) Received power in mobile station Eb (energy per bit) and Ec (energy per chip) Signal to interference ratio: Eb/N0 after despreading (Eb includes spreading gain and own cell interference reduced by OF) and Ec/(N0+I0) with interference power independent of OF (own cell, neighboring cells and noise) Total received interference and noise power Overall Max. achievable data rate (DL and UL) Max. achievable throughput (DL and UL) For each transmission mode at each pixel Min. required Tx power at MS (UL) and BS (DL) Max. received Rx power at MS (DL) and BS (UL) Max. achievable Ec/N0 and Eb/N0 in downlink and uplink Reception probability in downlink and uplink by AWE Communications GmbH 16
